Well, I'll still be looking to increase performance in libata, even such ;)

But stability before performance :)

Thank Promise, too. They are actively supporting my efforts on this
driver with hardware and docs. Promise has also provided Arjan (author
of "pdcraid") with documentation on their vendor-specific RAID format,
and they are making other efforts to better support open source, and be
more friendly with the open source community.
